Description
Technical field
The invention belongs to hypoid generating machine technical field, particularly relate to a kind of milling machine of digital-control spiral conical gear tool head.
Background technology
The design of automobile drive axle spiral bevel gear mainly adopts two kinds of tooth systems: i.e. convergent tooth and equal-depth teeth.The processing method that convergent tooth is traditional, at home and abroad applies widely for a long time.And in recent years, designing and calculating and the processing adjustment of equal-depth teeth obtain very large simplification, the adjustment of contact zone is also easier and quick simultaneously.Current automobile industry, equal-depth teeth gear obtains applying more and more widely, therefore can process convergent tooth, and the lathe processing again equal-depth teeth more and more obtains the favor of user.
Traditional tooth milling machine cutter spindle adopts cage chair transmission, namely cutting tool (cutterhead) is anchored on the main shaft of cage chair, and by means of the rotation of cage chair eccentric drum, cutting tool is installed on certain position, so not only can cause the loss of transmission accuracy and transmission efficiency, the movement velocity of cutter spindle also can be restricted simultaneously.Due to the restriction of above-mentioned tooth milling machine cutter spindle structure, interrupted division method can only be adopted at present to process screw-pinch bevel gear and hypoid gear, and continuous indexing can not be adopted to process cycloid equal-depth teeth bevel and hypoid gesrs, therefore, being badly in need of exploitation one can adopt interrupted division method to process screw-pinch bevel gear and hypoid gear, and continuous indexing can be adopted again to process the milling machine of digital-control spiral conical gear cutter spindle structure of cycloid equal-depth teeth bevel and hypoid gesrs.
Summary of the invention
The present invention provides a kind of reasonable in design, interrupted division method can be adopted to process screw-pinch bevel gear and hypoid gear for solving in known technology the technical problem that exists, and continuous indexing can be adopted again to process the milling machine of digital-control spiral conical gear tool head of cycloid equal-depth teeth bevel and hypoid gesrs.
The technical scheme that the present invention takes for the technical problem existed in solution known technology is:
Milling machine of digital-control spiral conical gear tool head, it is characterized in that: comprise cutter spindle casing, main shaft, spindle motor, first gear shaft, second gear shaft and clearance elimination gear, described cutter spindle casing is connected with the column side outer wall of tooth milling machine by three line slideways, spindle motor is connected with the first gear shaft by shaft coupling, and be fixed in the flange sleeve of tool head by bearing, described second gear shaft is arranged on the below of the first gear shaft, first gear shaft is meshed with the gear be arranged on the second gear shaft, main shaft is fixed on cutter spindle casing by bearing, at front-end of spindle, gear clearance elimination mechanism is installed, described rear-end of spindle is also equipped with encoder.
The present invention can also adopt following technical scheme:
Described gear clearance elimination mechanism comprises clearance elimination gear, driven gear and platen, and platen is connected with clearance elimination gear, driven gear by screw, be provided with disc spring in described driven gear, compresses driven gear, clearance elimination gear and platen by screw in compression disc spring.
Described clearance elimination gear is identical with the modulus of driven gear, and the number of teeth of clearance elimination gear is that the number of teeth of driven gear adds 1.
The advantage that the present invention has and good effect are: because the present invention adopts technique scheme, namely at front-end of spindle, gear clearance elimination mechanism is installed, the installation site of this gear clearance elimination mechanism is near front-end of spindle, so not only can increase cutter spindle rigidity, improve cutter spindle transfer motion power, but also rigidity and the cutting force of cutterhead can be strengthened, alleviate the wearing and tearing of cutterhead, and then realize adopting interrupted division method to process screw-pinch bevel gear and hypoid gear, continuous indexing can be adopted again to process the cutting of cycloid equal-depth teeth bevel and hypoid gesrs, considerably reduce Gear Processing cost.In addition, milling machine of digital-control spiral conical gear adopts this cutter spindle mechanism also can carry out high speed, accurately machining to spiral bevel gear, improves machining accuracy and the fineness of the flank of tooth, and then improves transmission accuracy and the transmission stability of spiral bevel gear.
